Application filed July 26, 1920. Serial No. 398,982.

To all whom it may concern:

Be it known that I, HORACE EAINEY, a

citizen of the United States, residing at Fort Branch, in the county ofGibson and State of Indiana, have invented new and useful Improvementsin Coal-Tipples, of which the following is a specification The inventionrelates to hoisting apparatus, being particularly adapted for thehandling of coal in the loading and unload-- ing thereof.

The invention appertains to coal tipples wherein two cars orplatformsare connected by means of a cable so that one acts as a counter-balancefor the-other, and wherein the hoisting cables are reversely wound onthe operating drum to cause one car to ascend while the other descendsand vice versa.

The invention provides a novel framing and arrangement of hoistingtackle, all as y will appear more fully hereinafter,reference being hadto the accompanying drawings in which,

Figure 1 is an elevation of a coal tipple embodying the invention. 7

Fig. 2 is a horizontal section on the line 2-2 of Fig. 1 showing theparts'on a-la scale.

Fig. 3 is a detail vertical section on the line 3-3 of Fig. 1 looking inthe direction of the arrow and showing the parts on a larger scale.

Corresponding and like parts are referred to in the followingdescription and indicated in the several views of the drawings by likereference characters.

The drawings illustrate a referred embodiment of the invention. owever,it is to be understood that in adapting the same to meet specificrequirements and conditions various changes in the form, proportion andminor details of construction may be resorted to without departing fromthe nature of the invention as claimed.

The tipple or apparatus illustrated embodies a framing upon which'ismounted two cars or platforms 1 and 2 which are adapted to movevertically in suitable shafts and which are directed in their verticalmovements by means of bars 3 which constitute parts of the framing. Theshafts 4L and 5 are disposed in close relation and may be of anysubstantial structure and are provided at the top with a series ofpulleys 6, 7 and 8 which give direction to the operatlng tackle such asthe cables. The cars or platforms 1 and .2 are connected by means of acable 9 which passes over the topmostpulley 6. It will thus beunderstood that one car 'orplatform acts as a counterbalance fortheother.

The pulley 6 is of such diameter that its op- .posite portions are inline with the vertical elements or parts of the cable 9. The severalpulleys are grooved in their outerv edges to provide seats to retain therespective cables in proper position against accidental lateraldisplacement. The pulleys 7 and 8 aredisposed in a lower plane than thepulley 6 and are located so as-to engage the respective end portions ofthe cable 9 which engage the grooves thereof to retain the severalcables in proper position. 7: The pulley 8 is arranged Wholly totheright of the right hand vertical portion .of the cable 9 so that theinner grooved edge of the pulley 8 receives the right hand end portionof the cable 9. The pulley 7 is likewise disposed wholly tothe right ofthe left hand end-poi tion of the cable 9 so that its outer grooved edgewill receive the left hand end portion of the cable 9. i i l The windingor hoisting drum 10 may be conveniently disposed, and adapted to beoperated in any preferred way. The hoisting cable 11 passing over thepulley 8 is connected to, the car'orplatform 2 and is adapt ed to windupon the drum 10. in a clockwisev direction. The cable 12 passingoverthe pulley 7 is connected to the car or platform l and is adapted towind upon the dru1n 10 in a counterclockwise direction. It will thus beunderstood that the cables 11 and 12 are.

reverselywound upon the operating drum 10 so that as oneof the cars orplatforms ascends the other descends'and vlce versa.

is applied to one end of the shaft 13 and suitable gearing 15 connectsthe shaft 13 with the drum whereby provision is had for manual operationof the hoisting drum.

The cars or platforms are of like construction, each embodying aplatform, up-

rights 16, cross bars 17 connecting corresponding uprights and crossbeams 18 connecting companion cross bars. Each of the cross beams 18 isprovided at a middle point with a short cross bar 19 to which is fitteda clevis 20 having a centrally disposed eye 21. A similar clevis 22 isattached at its ends to each of the cross beams 18 and is providedcentrally with an eye 23 which is interlooped with the eye 21. In thismanner the clevises 20 and 22 mutually brace each other. The respectivecables are connected with the interlooped eyes to the clevises therebyresulting in a substantial and firm connection. In the operation of theinvention the parts when assembled occupy the relative positionsubstantially as shown in the drawings. One of the cars or platformsacts as a counter-balance for the other. By having thehoisting cables 11and 12 reversely wound upon the hoisting drum 10 a minimum amount ofpower is required-to be expended for operating the cars because of thecounter-balancing.action of one upon the other. The power required :tobeef:- pended is such as to overcome inertia of the parts and move theexcess of load as will be readily understood. The end portions of thecable 9 are given positive direction because of their engagement withthe respective pulleys 7 and 8 whereby lateral displacement of the cablefrom the pulley 6 is guarded against.

What I claim is:

1. In hoisting apparatus of the character specified, a supportingframe-work including shafts, cars mounted in the shafts for verticalmovement, a cable connecting the cars whereby one of the cars acts as acounter-balance for the other car, a hoisting drum, hoisting cablesreversely wound upon 'the hoisting drum and connected with therespective cars, a guide pulley for the-cable connecting the cars andother guide pulleys disposed in a'lower plane than the first mentionedguide pulley and receiving the'hoisting cables and disposed to engagethe vertical end portions of the cable connecting the cars.

the interlooping eyes being adapted to receive the hoisting cable.

3.IIoisting apparatus of the character specified, embodying a framingincluding vertical shafts, cars mounted in the shafts for verticalmovement, a cable connecting the cars to admit of one car forming acounter-balance for the other car, hoisting cables connected withtherespective cars, a hoisting drum having the hoisting cables reversely'wound thereon, a'guide pulley of a diameter corresponding with thedistance between the centers of the shafts and receiving the cableconnecting the cars and grooved pulleys disposed in a plane below thebeforementioned pulley and receiving the hoisting cables and therespective vertical end portions of the cable forming connecting'meansbetween the two cars 7 1 4. Hoisting apparatus ofthe characterspecified, including a pair of shafts, a car mounted to travel in eachof the shafts, a

guide pulley of a diameter corresponding with the distance between thec'entersof the shafts, a cable running freely over the Tpul- HORACERAINEY.
